目的了解蚌埠市区健康体检人群脂肪肝的检出率及不同性别、年龄脂肪肝的分布特点。方法分析蚌埠市某三级医院健康体检中心2011—2012年收集的30 378例体检资料,按不同性别和年龄组统计脂肪肝检出率,比较不同性别、年龄脂肪肝检出率差异。结果体检人群脂肪肝检出率为28.24%,男性为33.85%,女性为11.20%;56岁以前男性脂肪肝检出率明显高于女性,差异有统计学意义(P<0.01);56岁以后男女脂肪肝的检出率相近,差异无统计学意义。男性检出率随年龄增加而增加,46~50岁出现峰值为38.71%,之后下降;女性随年龄增加脂肪肝检出率逐渐升高。25岁以后人群脂肪肝检出率明显升高。结论蚌埠市区男性是患脂肪肝的高危人群;与其他城市比较,蚌埠市区脂肪肝总体检出率不高;25岁以后是患脂肪肝的高危年龄段;男性46~50岁脂肪肝检出率最高,要引起重视,做好预防保健;女性更年期后脂肪肝检出率继续升高,要早期预防脂肪肝的发生。 Objective To understand the detection rate of fatty liver and the distribution characteristics of fatty liver of different gender and age in physical examination population of Bengbu city.
